Unknown escape character

the commands for one of my steps is:

"commands": [
    "find /secret/env-gitea-secret -maxdepth 1 -type f -exec echo {} \\; "
 ],"

when I try and run the step drone-runner kicks it out with ‘unknown escape character’

afaics this is valid yaml for “;” - which find needs…

Seems like this is a bug.
